Advanced German aircraft of World War 2, Planes of Fame Museum, Chino, California, 3 May 2019. German aviation technology led the world during World War 2, and here are thre examples. The Horten brothers built this Ho IV flying wing glider in 1943. Beneath it is a replica of the world's first jet aircraft, a Heinkel He 178 which first flew on 27 August 1939. Britain's Gloster E.28/39 did not fly until until 15 May 1941. Next to the 178 is an original Heinkel He 162A jet fighter built in 1944 - 45, one of a number captured at the end of WW2. Partly visible at top is a Japanese Yokosuka MXY-7 Ohka rocket-propelled suicide attack aircraft.
